The download for the second file has failed twice. I really appreciate what you're doing - developing this technique and writing it up - but how on Earth have you managed to make an .flv file which is 100MB when compressed?

edit: Got the file. Now to download 7zip...

edit2: So how do I combine the files? I opened the 7zip file manager, selected the first part, and selected File > Combine, but the output file can't be opened.

Same problem here. I have downloaded them a couple of times but none of the downloads will open no matter what extension or program I use.

Still trying to get everything else working, looks like when I get it figured out it will be a great tool.

Thanks for taking the time Zaxxon to make all this posible.

Edit: Got it working by using the post previous to this one.

Just open .001 file.
(Right click, 7zip, Open file)

Whether I go to Open Archive and double click this, or Extract File, the only thing that comes out is this:
http://catmanofiowa.com/RSoul/img/sz_extracted.gif

It's 105MB but I cannot play it, not even after installing VLC Medial Player.

 

[zaxxon]

It is not 105MB. First File is 70MB, second one 62MB. Perhaps one of them has been not completely downloaded?

You should see file gmsh.flv when opened.


I will upload them to a different server tonight. Tomorrow I will give you new links.

 

[R Soul]

Right. My copy of the first file was about 44MB, so the download must have terminated. I'm surprised 7zip didn't produce any error messages.

edit: Re-downloaded the first file in full. The .flv works now, but if you compress it with 7zip you can get one file which is 61.6MB.

 

[zaxxon]

Ok. I didn't try to compress. I thought this kind of video files are not suitable for compression. I was wrong. I will delete the two parts and upload all in one single file compressed.

How do you create the lamalla2.mat in the terrain folder?

 

[liquido]

simply change the name of the file....

you must create at firts the file "lamalla2.mat"

to generate "lamalla2.mat" use higer values for grid size... example:

lamalla2.mat

makegrid(-10000,10000,-6000,6000,200)

lamalla.mat

makegrid(-5000,5000,-3000,-3000,30)

when you call the scripts "makegrid" a file called "necesidades" is made and needed in the next step "readgrid" to elevate the grid... so you have to create your grid with higer values to generate the first file that you will change the name to "lamalla2.mat" and after that go back to "makegrid" and repeat the process.

 

[Jon Sheldon]

So I have to use the makegrid? I cant just use the seamless server info?

 

[zaxxon]

How do you create the lamalla2.mat in the terrain folder?

You can run make_grid/read_grid inside folder s2_elevation for generating lamalla.mat and inside s2_elevation_b for generating also lamalla.mat (but this last one will be later renamed as lamalla2.mat)

The parameters for make_grid must be this way (as liquido :thanks:said):

1) for lamalla.mat: at least all the road must be covered (use 100m extra)
2) for lamalla2.mat: all the road and terrain must be covered (use extra margin)

In the last version of the scripts when you run coge_datos inside s4_terrain, lamalla.mat of folder s2_elevation_b is automatically copied inside s4_terrain renamed as lamalla2.mat

You can open coge_datos.m and read its content:

system('copy ..\s2_elevation\salida\lamalla.mat .');
system('copy ..\s2_elevation_b\salida\lamalla.mat lamalla2.mat');

So I have to use the makegrid? I cant just use the seamless server info?

You can use leer_gridfloat or make_grid/read_grid. Both create lamalla.mat

 

[Jon Sheldon]

Great, thanks again.

Eventhough the video was in spanish I was able to under stand how to use gmsh. Thanks again.

 

[Jon Sheldon]

I got this when I ran coge_datos in s4_terrain folder.

1 file(s) copied
1 file(s) copied

En Z (lamalla2,.msh)

Sorry for asking so many questions.

 

[zaxxon]

Those messages are the result of checking if your elevation data is enough for your terrain mesh.

In coordinate X you have elevation data for points in the interval [-1678,2155]. But in X coordinate your mesh (made with gmsh) needs elevation values for points that lie in range [-2980,3004]
So, the conclusion is that you haven't enough elevation data. You need data from a bigger grid.

The same idea applies for coordinate Z.

You can't go on with the process. Create a smaller mesh with gmsh or get elevation data for wider surface.

 

[Jon Sheldon]

Thanks again.

 

[Jon Sheldon]

5 days of trying but cant get xml to load in btb. Still going to try to see if I can figure this out. Will post if I get it loaded.

 

[R Soul]

Are all the XPacks in place? I.e. create a new folder for your project, put a copy of each necessary Xpack zip file in the XPacks folder.

You can open the XML file with a text editor to see what XPacks it needs.

Another possibility is that the file is not formatted correctly, so you may have to find an old BTB XML file and compare them.

 

[zaxxon]

Give me a link for downloading the Venue.xml and I will try to find the problem.

 

[Jon Sheldon]

Here is the link. http://www.beerbelliesbrew.com/downloads/venue.zip

I left the walls out of the file.

Thanks again.

 

[zaxxon]

Here is the link. http://www.beerbelliesbrew.com/downloads/venue.zip

I left the walls out of the file.

Thanks again.

You have to insert s4_terrain\salida\listado_anchors.txt just after <Terrain> keyword, before TerrainAreas. Then try again, and if you still can't open it, give me again the Venue.xml. It is a good idea to split the track and terrain. Well done.

 

[Rubinhofan]

Well, I also used the zaxxon-technique, but I´ve a problem at "step 7: join the parts"

It seems that surfaces.txt is missing. The previous steps worked without problems. I hope you can help me

 

[zaxxon]

Das ist kein Problem
It is an old error message. Just go on, insert inside the Venue.xml the list of TerrainAreas and substitute the list of tracks. You can also insert the protection walls. The project should open without problems.

If you want to add the automatically generated pacenotes you should first declare a valid list of driveline segments. Otherwise BTB wiil not open the project.

Guten glück
